The outputs are protected against continuous overload,
open-circuit, and short-circuit. Full n+1 redundant operating
mode is made possible by integrated ORing FETs/diodes.
When several converters are connected in parallel, a
single-wire connection between converters ensures current
sharing.
The converters are designed as two or three separate
forward converters with fixed switching frequency and
synchronous rectifiers at their output.
LEDs on the front panel and various warning signals display
the status of the converter. The aluminum case acts as a
heat sink and as an RFI shield. It is designed for vertical
insertion into 19" rack systems, but it can also be mounted
in any other position, as long as the necessary airflow is
ensured. The connector is a 47-pin type from Positronic.

Functional Description
The converter input is protected against surges and
transients occurring on the source lines. The highly ef ficient
input filter and the active inrush current limiter ensure a very
low inrush current of short duration. This prevents circuit
breakers and fuses from tripping at switch-on.
All CPA models have an additional bridge rectifier and a
boost converter to provide active power factor correction
according to EN 61000-3-2.
The CPx200/250 models (see fig.1a) are equipped with two
independent high efficiency 2-switch forward converters,
switching 180° out of phase to minimize ripple current at the
input. Both forward converters are fully regulated.
On the secondary side, two high current synchronous
rectifiers supply the 5 V and 3.3 V outputs with up to 60 A.
The secondary controlled +12 V post regulator is supplied
by an additional winding of the 3.3 V main transformer, and
the linear regulator for the –12 V output is supplied by the
output choke of the +12 V output. After rectification, the
output filter reduces ripple and noise to a minimum without
compromising the dynamic response.
All outputs are protected from the bus by decoupling FE Ts
or diodes. A current monitor calculates the output power. As
Fig. 1a
Block diagram of CPA/CPD200 and CPA/CPD250
models. For pin allocation see Mechanical Data.
soon as the output power exceeds the maximum threshold
level, the converter starts to reduce the output power by
decreasing the output voltages.
In contrast to the outputs Vo1 (5 V), Vo2 (3.3 V), and Vo3
(+12 V) with active current sharing, output Vo4 (12 V) has a
droop characteristic for passive current sharing. The
switching frequency is typically 135 kHz.
CPA500/550 models (see fig. 1b) exhibit a third forward
converter for the outputs Vo3 (+12 V) and Vo4 (12 V). All
outputs are fully regulated.
If for some reason the voltage of any output exceeds the
nominal value significantly, the converter is permanently shut
down. If option L is fitted, this occurs as well, if the max.
output current is exceeded for a predefined time. To reset,
the input voltage must be removed.
Power-One's Efficient Dual Geometric Edge Technology
(EDGETM) facilitates high current density, increases
reliability by reducing component stresses, and decreases
the amount of heat dissipated. The backbone of this
patented technology is an interleaved, multi-channel
forward converter utilising a transitional resonant switching
technique and proprietary leading and trailing-edge pulse
width modulation. It has a proven track record in high-
availability power solutions.

BCD20005-G Rev. AC, 29-Oct-08 Page 6 of 20 www.power-one.com
Inrush Current Limitation
The converters incorporate an active inrush current limiter
in the input circuitry, which reduces the peak inrush current
value by a factor of 10 15 to protect connectors and
switching devices from damage.
Note: The inrush current limitation is achieved using
electronic circuitry. For effective limitation the converter
should not be switched on and off more frequently than every
8 seconds.
Reverse Polarity
To avoid unwanted power losses, the CPD Series
converters are not protected against reverse polarity at the
input. In case of reversed input voltage, the input
suppressor diode will be conducting and trigger the input
fuse to blow; however no further damage will occur.
The CPA Series converters are designed for AC input and
have a rectifier bridge on the input.
Efficiency
The efficiency is specified in table 1. Fig. 2 shows the
dependence on input voltage (CPA models). The efficiency
of CPD models depends only marginally on input voltage.
Fig. 2
CPA Series: Efficiency versus input voltage
Input Transient Protection
A metal oxide VDR (Voltage Dependent Resistor) together
with the input fuse form an effective protection against high
input voltage transients, which typically occur in most
installations.
Input Fuse
An incorporated miniature slow-blow fuse protects the
converter against further damage in the case of a failure.
Reverse polarity applied to the input of CPD models will
cause the fuse to blow but without other damage.
Note: The fuse is not customer-accessible.

Hold-up Time of CPD Models
For extended hold-up time of CPD models, use external
output capacitors or decoupling diodes and input capacitors
of adequate size.
Formula for additional external input capacitor:
2 • Po • (th totalth) • 100
Ci ext = –––––– –––––––––––––
η • (Vti2Vi min 2)
where as:
Ci ext = external input capacitance [mF]
Po= output power [W]
η= efficiency [%]
th total = total hold-up time [ms]
th= hold-up time [ms]
Vi min = minimum input voltage [V]
Vti = threshold level [V]
Note: After Vi was removed, the outputs maintain their
voltage for the time th. Even if Vi comes back during th, but
after tbo, the output voltage will be affected.
Hot Swap
Hot swap is possible. The output voltages may deviate
dynamically by 5% during the plug-in / plug-out operation.
Output Characteristic and Protection
All outputs are fully protected against continuous open-
circuit (no load) and continuous short-circuit conditions.
All outputs of CPx200/250 models have a constant current
limitation with a rectangular characteristic; see figure 3. In
addition, the total power from outputs Vo1, Vo2, and Vo3 is
limited to Po max, resulting in a free choice of load distribution
between these outputs. Output Vo4 is disabled in the case
of overtemperature generated by overcurrent.
In CPA500/550 models, the total power of all four output s is
limited to Po max.
In all models, all outputs are monitored for overvoltage
condition. If an overvoltage of 120 – 130% is dedected, the
converter is permanently disabled. To reset, the input
voltage must be removed for 60 seconds.
Thermal Considerations
If a converter is mounted in the upright position with airflow
as specified in the general conditions of table 4 and 5,
allowing unrestricted forced-air cooling, and is operated at

open-circuit (not connected). If pin 39 is connected to a return
pin (e.g., pin 22), the internal logic will disable all outputs. The
inhibit input is protected by a decoupling diode.
The enable pin 27 (EN#) must be connected to a return pin
(e.g., pin 22) enable the converter . Pin 27 is shorter than the
others ensuring startup only, when all other pins are already
connected to the system providing true hot-swap capability.

Output filter reducing the output ripple of Vo1 and Vo2
its nominal input voltage and power at maximum ambient
temperature TA max (see Temperatures), the temperature
measured at the measurement point of the case
temperature TC (see Mechanical Data) will approach after
an initial warm-up phase the indicated maximum value of
TC max (105 °C) . However, the relationship between TA and
TC depends heavily on the operating conditions and system
integration. The thermal conditions are significantly
influenced by the input voltage, the output current, the
airflow, and the temperature of the adjacent elements and
surfaces. TA max is therefore only an indicative value
(contrary to TC max).
Caution: The installer must ensure that under all operating
conditions TC remains within the limit s shown in the diagrams
of fig. 4.
Note: Forced-air cooling or an additional heat sink can
improve the reliability or allow TA to be increased above
TA max, provided that TC max is not exceeded.
Thermal Protection
A temperature sensor fitted on the main PCB provides an
overtemperature warning (degrade) signal 15 °C below the
temperature Tc max, at which the thermal derating begins to
reduce the output power. The output power returns to the
normal value, when the temperature drops back below this

Fig.10
Power Fail: JFET output, IFAL# 10 mA
Power Fail Signal
The power fail circuitry monitors the input voltage and all
output voltages. It s output signal VFAL# changes from high to
low impedance (<0.5 V), when one of the monitored
voltages falls below the threshold level; VFAL# changes back
to high impedance, when all monitored voltages exceed
their threshold level.
The threshold levels correspond to approx. 85% of Vo nom.
Vi min of CPD200/250 up to Version V116 and CPA200/250
up to Version V115 is not monitored.
Sense Lines
(Only for Vo1, Vo2, and Vo3.)
This feature allows the compensation of voltage drops
across the connector contacts and if necessary, across the
load lines.
To ensure correct operation, all sense lines S+ (V o1SENSE,
Vo2SENSE, and Vo3SENSE) should be connected to the
respective power outputs. The common sense return S–
(SRTN) should be connected to RTN (pin 5 – 12).
Note: Open sense lines are admissible, but the output
voltage regulation will be poor.
The voltage difference between any sense line at its
respective power output pin (as measured on the
connector) should not exceed the following values.
Note: If the sense lines S+ and S– compensate for a
considerable voltage drop, the output loads shall be reduced
in order to respect the maximum output power.
Temperature Warning and Shutdown
A temperature warning circuitry monitors the case
temperature TC. Its output signal VDEG# changes from high
to low impedance, when the TC exceeds the upper threshold
level, and changes back to high impedance, when TC falls
below the lower threshold level, which is 85 °C ± 5 °C.
Pin 38 (degrade signal DEG#) is internally connected via the
collector-emitter path of an NPN transistor to the signal
return pin 22. The current IDEG# through pin 38 should not
exceed 40 mA, and VDEG# should not exceed 40 V.
If TC exceeds 105 °C, the converter will be disabled. It
resumes operation automatically, once TC falls below 105 °C.

Active Current Sharing for Vo1, Vo2, Vo3
The current sharing facility, consisting of a single-wire link,
should be used, where several converters are operated in
parallel connection, for example, high reliability n+1
redundant systems or systems providing higher output
power.
Note: Not more than six converters should be connected in
parallel.
Using this feature reduces the stress of the individual
converters and improves the reliablity of the system.
Interconnection of the current sharing terminals causes the
converters to share the output current evenly. In n+1
redundant systems a failure of a single converter will not
lead to a system failure, since the outputs are already
decoupled by FETs and diodes internally. Fig. 11

Installation Instructions
These converters are components, intended exclusively for
installation within other equipment by an industrial
assembly process or by a professionally, competent
person. Installation must strictly follow the national safety
regulations in respect of the enclosure, mounting, creepage
distances, clearance, casualty markings, and segregation
requirements of the end-use application.
Connection to the system shall be made via the mating
female connector (see fig. 16). Other installation methods
may not meet the safety requirements. Check for hazardous
voltage before altering any connections.
The converters are provided with a leading pin no. 45, which
is reliably connected to the case. For safety reasons it is
essential to connect this pin to the protective earth of the
supply system; see also Safety of Operator-Accessible
Output Circuits.
The Vi input (pin no. 46) is internally fused. This fuse is
designed to protect the converter in case of over current,
but may not be able to satisfy all customer requirements.
External fuses in the wiring to one or both input pins (no. 46
and/or no. 47) may therefore be necessary to ensure
compliance with local requirements.
Important: If the inhibit function is not used, pin 39 (i) should
be left unconnected to enable the outputs. Enable Pin 27
(EN#) should be connected to pin 22 (RTN) to enable the
outputs.
Do not open the converters, or the warranty will be
invalidated. Make sure that there is sufficient airflow
available for convection cooling. This should be verified by
measuring the case temperature, when the converter is
installed and operated in the end-use application. The
maximum specified case temperature TC max should not be
exceeded.
Make sure that a converter failure (e.g., by an internal short-
circuit) does not result in a hazardous condition.
